     THIS AGREEMENT is entered into by and between TeleCorp PCS, Inc., a
Delaware Corporation (the "Company"), and Julie Dobson, an employee of the

     WHEREAS, the Executive renders important services to the Company or a
subsidiary of the Company, and the Company desires to award shares to the
Executive under the Plan;

     NOW, THEREFORE, in consideration of the foregoing and the mutual agreements
herein contained, the parties hereto hereby agree as follows:

     1.   Issuance of Grant Shares.  The Company hereby grants to the Executive
          ------------------------
and the Executive hereby accepts from the Company upon the terms and conditions
hereinafter set forth, 2,287.21 shares of Series E Preferred Stock of the

the Executive one or more certificates in her name for the Grant Shares. The
Grant Shares will be validly issued and outstanding, fully paid and non-
assessable. The Grant Shares will be held by the Company in the name of the
Executive until fully vested pursuant to Section 4, below.

     2.   Other Conditions and Limitations.  The Grant Shares are granted on the
          --------------------------------
condition that the receipt of the Grant Shares hereunder shall be for investment
purposes and not with a view to resale or distribution, except that such
condition shall be inoperative if the reoffering of


Grant Shares is registered under the Securities Act of 1933, as amended, or if
in the opinion of counsel for the Company such Grant Shares may be resold
without registration.

     3.   Relationship to Plan.  The Grant Shares granted pursuant to this
          --------------------
Agreement have been granted pursuant to the Plan and are in all respects subject
to the terms, conditions and definitions of the Plan.  The Executive hereby
accepts the Grant Shares subject to all the terms and provisions of the Plan and
agrees that all decisions and the interpretations of the Plan by the
Compensation Committee of the Board of Directors of the Company (the
"Committee") shall be final, binding and conclusive upon the Executive and her
heirs.

     4.   Forfeiture of Grant Shares.  The Grant Shares shall vest in accordance
          --------------------------
with the schedule set forth on Schedule B of the Plan. In addition, the
following forfeiture provisions are hereby imposed upon the Grant Shares and
shares issued in respect of such Grant Shares as share dividends or as share
splits, or otherwise (the term "Grant Shares" as used in this Agreement to
include all such shares):

          (a)  Except as provided in paragraph (b), the Executive must remain
     employed by the Company or any of its subsidiaries during the vesting
     periods set forth on Schedule B of the Plan to vest in such Grant Shares.
                          ----------
     If the Executive fails to satisfy such requirements and is not otherwise
     vested under paragraph (b), the Executive shall forfeit and transfer to one
     or more persons designated by the Committee, all unvested Grant Shares
     granted pursuant to this Agreement.

          (b)  If the Executive's employment with the Company or one of its
     subsidiaries terminates prior to vesting in any Grant Shares issued
     pursuant to this Agreement by reason of her retirement under a retirement
     plan maintained by the Company or one of its subsidiaries, the Committee
     may, in its sole discretion, specify that the Executive become vested at
     that time, at a future date or upon the completion of such other conditions
     as the Committee, in its sole discretion, may provide.

          (c)  Executive further agrees that the Grant Shares shall be subject
     to repurchase by the Company at a repurchase price of $.01 per share in
     accordance with the terms of Exhibit A attached hereto.
                                  ---------

                                       2


          (d)  Within 30 days of an event giving rise to a forfeiture under
     paragraphs (a) or (b) hereof, the Executive shall deliver to one or more
     persons specified by the Committee, all certificates representing the Grant
     Shares which have been forfeited together with stock powers validly
     assigning such Grant Shares to such other persons as the Committee may
     designate.  The Company shall make no payment to the Executive with respect
     to any Grant Shares so forfeited.

          (e)  If the Executive fails to comply with any of the provisions of
     this Section 4, the Company, at its option and in addition to its other
     remedies, may suspend the rights of the Executive to vote and to receive
     future dividends on the Grant Shares which have been forfeited or may
     refuse to register on its books any transfer or change in the ownership of
     the Grant Shares which have been forfeited or in the right to vote thereon,
     until the provisions of this Section 4 are complied with to the
     satisfaction of the Company.  To ensure compliance with the terms of this
     Agreement, the Company may issue to its transfer agent appropriate stop
     transfer instructions with respect of the Grant Shares (including without
     limitation any vested Grant Shares).

     5.   Nontransferability of Shares.  Any Grant Shares which are not vested,
          ----------------------------
as specified in Section 4 above, shall be non-transferable by the Executive.
Transfer of Grant Shares which are vested is further restricted pursuant to the
terms of a Stockholders' Agreement by and among Executive, the Company, AT&T
PCS, TWR Cellular and the Cash Equity Investors, TeleCorp Investors and
Management Stockholders identified therein, executed as of the date hereof (the

          ---------------------
this Agreement, the Executive shall have all of the rights of a shareholder of
the Company with respect to the Grant Shares registered in her name, including
the right to vote such Grant Shares and receive the dividends and other
distributions paid or made with respect to such Grant Shares.

     8.   No Employment Commitment; Tax Treatment.  Nothing herein contained
          ---------------------------------------
shall be deemed to be or constitute an agreement or commitment by the Company to
continue the Executive in its employ.  The Company makes no representation about
the tax treatment to the

                                       3


Executive with respect to receiving, holding or disposing of the Grant Shares,
and the Executive represents that she has had the opportunity to discuss such
treatment (including the application of Section 83 of the Code) with her tax
adviser.

     9.   Governing Law.  This Agreement shall be subject to and construed in
          -------------
accordance with the law of Commonwealth of Delaware.

     10.  Withholding Tax.  The Company shall have the right to require the
          ---------------
Executive to pay the Company the amount of any taxes which the Company is or
will be required to withhold with respect to the Grant Shares.

     IN WITNESS WHEREOF, the Company and the Executive have executed this
Agreement in duplicate on this 16th day of July, 1998.

steps necessary to accomplish such repurchase.  From time to time, upon
Executive's request, the Escrow Holder shall: (i) cancel the certificate(s) held

First Offeree by giving written notice (a "Purchase Notice"), that the First
Offeree desires to purchase all (and not less than all) of such Offered Shares
from the Seller, to the Stockholders (other than the Seller) and the Company not

provided, however, that if such purchase is subject to the consent of the FCC or

any public service or public utilities commission, the purchase of the Offered

             (c)    If the First Offeree declines (which shall include the
failure to give timely notice of acceptance) to purchase all of the Offered
Shares subject to the First Offer within the First Offer Period, the Seller
shall have the right (for a period of ninety (90) days following the expiration
of the First Offer Period) to consummate the sale of the Offered Shares to any
person; provided, however, that the purchase price of such Offered Shares
        --------  -------
payable by such person must be at least equal to the cash purchase price thereof
set forth in the Offer Notice and all other terms and conditions of any such
sale shall not be more beneficial to such third party than those contained in
the Offer Notice. If any Offered Shares are not sold pursuant to the provisions
of this Section 2.2 prior to the expiration of the ninety (90) day period
specified in the immediately preceding sentence, such Offered

                                      -8-


Shares shall become subject once again to the provisions and restrictions
hereof; provided, however, that if such purchase is subject to the consent of
        --------  -------
the FCC or any public service or public utilities commission, the purchase of
the Offered Shares shall be closed on the first business day after all such
consents shall have been obtained by Final Order.

pursuant to this Section 2.2 shall be payable in cash by certified bank check or
by wire transfer of immediately available funds.

any single transaction or series of related transactions to one or more Persons
(each such Person an "Inclusion Event Purchaser") shares of any series or class
of stock issued by the Company (collectively, "Inclusion Stock") in
circumstances in which, after giving effect to such Transfer, whether acting
alone or in concert with any other Stockholder (such parties referred to herein
as "Selling Stockholders") would result in such Selling Stockholder(s)
Transferring twenty-five percent (25%) or more of the outstanding shares of any
such class of Inclusion Stock outstanding on the date of such proposed Transfer
on a fully diluted basis (an "Inclusion Event"), unless the terms and conditions
of such sale to such Inclusion Event Purchaser shall include an offer to AT&T
PCS, the Cash Equity Investors, and the Management Stockholders (each, an
"Inclusion Event Offeree") to Transfer to such Inclusion Event Purchasers up to
that number of shares of any class of Inclusion Stock then beneficially owned
(as defined in the Securities Exchange Act of 1934) by each Inclusion Event
Offeree that bears the same proportion to the total number of shares of
Inclusion Stock at that time beneficially owned (without duplication) by each
such Inclusion Event Offeree as the number of shares of Inclusion Stock being
Transferred by the Selling Stockholders (including shares of Inclusion Stock
theretofore Transferred if in any applicable series of related transactions)
bears to the total number of shares of Inclusion Stock at the time beneficially
owned (without duplication) by the Selling Stockholders (including shares of
Inclusion Stock theretofore Transferred if in any applicable series of related
transactions). If the Selling Stockholders receive a bona fide offer from an
Inclusion Event Purchaser to purchase shares of Inclusion Stock in circumstances
in which, after giving effect to such sale would result in an Inclusion Event,
and which offer such Selling Stockholders wish to accept, the Selling
Stockholders shall then cause the Inclusion Event Purchaser's offer to be
reduced to writing (which writing shall include an offer to purchase shares of
Inclusion Stock from each Inclusion Event Offeree according to the terms and
conditions set forth in this Section 2.3) and the Selling Stockholders shall
send written notice of the Inclusion Event Purchaser's offer (the "Inclusion
Notice") to each Inclusion Event Offeree, which Inclusion Notice shall specify
(i) the names of the Selling Stockholders, (ii) the names and addresses of the
proposed acquiring Person, (iii) the amount of shares proposed to be Transferred
and the price, form of consideration and other terms and conditions of such
Transfer (including, if in a series of related transactions, such information
with respect to shares of Inclusion Stock theretofore Transferred), (iv) that
the acquiring Person has been informed of the rights provided for in this
Section 2.3 and has agreed to purchase shares of Inclusion Stock in accordance
with the terms hereof, and (v)

                                      -9-


the date by which each other Selling Stockholder may exercise its respective
rights contained in this Section 2.3, which date shall not be less than thirty
(30) days after the giving of the Inclusion Notice. The Inclusion Notice shall
be accompanied by a true and correct copy of the Inclusion Event Purchaser's
offer. At any time within thirty (30) days after receipt of the Inclusion
Notice, each Inclusion Event Offeree may accept the offer included in the
Inclusion Notice for up to such number of shares of Inclusion Stock as is
determined in accordance with this Section 2.3, by furnishing written notice of
such acceptance to each Selling Stockholder, and delivering, to an escrow agent
(which shall be a bank or a law or accounting firm designated by the Inclusion),
on behalf of the Selling Stockholders, the certificate or certificates
representing the shares of Inclusion Stock to be sold pursuant to such offer by
each Inclusion Event Offeree, duly endorsed in blank, together with a limited
power-of-attorney authorizing the escrow agent, on behalf of the Inclusion Event
Offeree, to sell the shares to be sold pursuant to the terms of such Inclusion
Event Purchaser's offer.

     In the event that the Inclusion Event Purchaser does not agree to purchase
all of the shares of Inclusion Stock proposed to be sold by the Selling
Stockholders and the Inclusion Event Offerees, then each Selling Stockholder and
Inclusion Event Offeree shall have the right to sell to the Inclusion Event
Purchaser that number of shares of Inclusion Stock as shall be equal to (x) the
number of shares of Inclusion Stock which the Inclusion Event Purchaser has
agreed to purchase times (y) a fraction, the numerator of which is the number of
shares of Inclusion Stock beneficially owned (without duplication) by such
Selling Stockholder or Inclusion Event Offeree and the denominator of which is
the aggregate number of shares of Inclusion Stock beneficially owned (without
duplication) by all Selling Stockholders and Inclusion Event Offerees.  If any
Inclusion Event Offeree desires to sell less than its proportionate amount of
shares of  Inclusion Stock that it is entitled to sell pursuant to this Section
2.3, then the Selling Stockholders and the remaining Inclusion Event Offerees
shall have the right to sell to the Inclusion Event Purchaser an additional
amount of shares of Inclusion Stock as shall be equal to (x) the number of
shares of Inclusion Stock not being sold by any such Inclusion Event Purchasers
times (y) a fraction, the numerator of which is the number of shares of
Inclusion Stock owned such Selling Stockholder or remaining Inclusion Event
Offeree and the denominator of which is the aggregate number of shares of
Inclusion Stock beneficially owned (without duplication) by all Selling
Stockholders and remaining Inclusion Event Offerees.  Such process shall be
repeated in series until all of the remaining Inclusion Event Offerees agree to
sell their remaining proportionate number of shares of Inclusion Stock.

             (b)    The purchase from each Inclusion Event Offeree pursuant to
this Section 2.3 shall be on the same terms and conditions, including the price
per share received by the Selling Stockholders and stated in the Inclusion
Notice provided to each Inclusion Event Offeree.

             (c)    Simultaneously with the consummation of the sale of the
shares of Inclusion Stock of the Selling Stockholders and each Inclusion Event
Offeree to the Inclusion Event Purchaser pursuant to the Inclusion Event
Purchaser's offer, the Selling Stockholders shall notify each Inclusion Event
Offeree and shall cause the purchaser to

                                     -10-


remit to each Inclusion Event Offeree the total sales price of the shares of
Inclusion Stock held by each Inclusion Event Offeree sold pursuant thereto and
shall furnish such other evidence of the completion and time of completion of
such sale and the terms thereof as may be reasonably requested by each Inclusion
Event Offeree.

             (d)    If within thirty (30) days after receipt of the Inclusion
Notice, an Inclusion Event Offeree has not accepted the offer contained in the
Inclusion Notice, such Inclusion Event Offeree shall be deemed to have waived
any and all rights with respect to the sale described in the Inclusion Notice
(but not with respect to any subsequent sale, to the extent this Section 2.3 is
applicable to such subsequent sale) and the Selling Stockholders shall have
sixty (60) days in which to sell not more than the number of shares of Inclusion
Stock described in the Inclusion Notice, on terms not more favorable to the
Selling Stockholders than were set forth in the Inclusion Notice; provided,
                                                                  --------
however, that if such purchase is subject to the consent of the FCC or any
- -------
public service or public utilities commission, the purchase of the Offered
Shares shall be closed on the first business day after all such consents shall
have been obtained by Final Order.

     Section 2.4    Right of First Negotiation. In the event that Executive
     ------- ---    --------------------------
desires to Transfer any shares of Common Stock following the IPO Date in a
Transfer described in Section 2.1(b), she shall give written notice thereof to
AT&T PCS, such notice to specify, among other things, the number of shares that
she desires to sell.  For the applicable first negotiation period hereinafter
set forth, AT&T PCS shall have the exclusive right to negotiate with Executive
with respect to the purchase of such shares; it being understood and agreed that
such exclusive right shall not be deemed to be a right of first offer or right
of first refusal for the benefit of AT&T PCS and Executive shall have the right
to reject any offer made by AT&T PCS during such applicable first negotiation
period.  Upon the expiration of such applicable first negotiation period,
Executive shall have the right (for the applicable offer period hereinafter set
forth with respect to each applicable first negotiation period), following the
expiration of such applicable first negotiation period, to offer and sell such
shares included in such written notice on such terms and conditions as shall be
acceptable to such Executive in her sole discretion.  If any of such shares
included in such written notice are not sold pursuant to the provisions of this
Section 2.4 prior to the expiration of  the applicable offer period, such shares
shall become subject once again to the provision and restrictions hereof.

     If Executive desires to Transfer shares of Common Stock pursuant to Rule
144, the applicable first negotiation period shall be three (3) hours (it being
understood and agreed that Executive shall, in addition to giving written notice
of such proposed Transfer by facsimile, use commercially reasonable efforts to
contact AT&T PCS by telephone) and the applicable offer period upon the
expiration of such first negotiation period shall be five (5) business days, and
in any single transaction or series of related transactions to one or more
persons which will result in the Transfer by Executive (together with any other
Stockholder participating in such single transaction or series of related
transactions) of not more than ten percent (10%) of the Common Stock on a fully
diluted basis (excluding for such purposes the Series A Preferred Stock), the
applicable first negotiation period shall be one (1) business day, so long as
notice of such proposed Transfer is given to AT&T PCS

                                     -11-


prior to 9:00 A.M. on the day prior to the date of such proposed Transfer (it
being understood and agreed that Executive shall, in addition to giving written
notice of such proposed Transfer by facsimile, use commercially reasonable
efforts to contact AT&T PCS by telephone) and the applicable offer period upon
the expiration of such first negotiation period shall be ten (10) business days.

     Section 2.5    Additional Conditions to Permitted Transfers.
     ------- ---

             (a)    Upon any Transfer pursuant to Section 2.2 or Section 2.3,
each Transferee that is not a party hereto shall, prior to such Transfer, agree
in writing to be bound by all of the provisions of this Agreement applicable to
Executive (and shall thereby become a Stockholder for all purposes of this
Agreement). Any Transfer without compliance with such provisions of this
Agreement shall be null and void and such Transferee shall have no rights as a
Stockholder of the Company.

             (b)    Notwithstanding anything to the contrary contained in this
Agreement, Executive agrees that she will not effect a Transfer of shares of
Company Stock to anyone prohibited by the Company; provided, however, that
                                                   --------  -------
nothing contained in this Section 2.5(b) shall be construed to prohibit a
Transfer of Common Stock by Executive after the IPO Date pursuant to an
underwritten registration or in accordance with the provisions of Rule 144.

     Section 2.6    Representations and Warranties. A Stockholder purchasing
     ------- ---    ------------------------------
shares of Company Stock pursuant to Section 2.2 shall be entitled to receive
representations and warranties from the transferring Stockholder that such
Stockholder has the authority (corporate or otherwise) to sell such shares, is
the sole owner of such shares, and has good and valid title to such shares, free
and clear of any and all Liens (other than pursuant to this Agreement, the
Restated Certificate or any Related Agreement), and that the sale of such shares
does not violate any agreement to which it is a party or by which it is bound.

     Section 2.7    Stop-Transfer.
     ------- ---

             (a)    The Company agrees not to effect any Transfer of shares of
Company Stock by Executive whose proposed Transfer is subject to Sections 2.2,
2.3 or 2.4 until it has received evidence reasonably satisfactory to it that the
rights provided to any other Stockholders pursuant to such Sections, if
applicable to such Transfer, have been complied with and satisfied in all
respects. No Transfer of any shares of Preferred Stock and/or Common Stock shall
be made except in compliance with all applicable securities laws. Any Transfer
made in violation of this Agreement shall be null and void.

reorganization, or any other form of recapitalization, or consolidation, or
merger, or share split, or share dividend, or which are acquired by Executive or
her Affiliated Successors in any other manner.

             (b)    Whenever the number of outstanding shares of Equity
Securities is changed by reason of a stock dividend or a subdivision or
combination of shares effected by a reclassification of shares, each specified
number of shares referred to in this Agreement shall be adjusted accordingly.

     Section 3.2    Amendment of Restated Certificate.  Whenever the number of

shares of authorized Common Stock is not sufficient in order to issue shares of
Common Stock upon conversion of Preferred Stock in accordance with the Restated
Certificate, (i) the Company shall promptly amend the Restated Certificate in
order to authorize a sufficient number of shares of Common Stock, and (ii)
Executive agrees to vote her shares of Preferred Stock and Common Stock in favor
of such amendment.

things, for the granting of certain restrictions on the sale, transfer, pledge,

Certificate, and that under certain circumstances, the holder hereof may be
required to sell the shares represented by this Certificate.  By acceptance of
this Certificate, each holder hereof agrees to be bound by the provisions of
